PROBLEM TO BE SOLVED: To provide a calking apparatus with which the only desired part of a workpiece is plastically deformed. SOLUTION: A calking part 3 is provided with a plurality of rollers 32 which are freely rotatably provided on the main body part 31 and, when plastically deforming the bearing member 81 of a workpiece with the calking part 3, the main body part 31 is rotationally driven with a driving motor 5 and, as the result, the rollers 32 are rotated so as to roll while pressing the bearing member 81 by the outer peripheral surface. Then, the only desired part of the bearing member 81 is gradually plastically deformed. COPYRIGHT: (C)2004,JPO
